基于weather tool的蒸发冷却空调的舒适性研究
Research on comfort of evaporative cooling air conditioning based on weather tool software
摘要：
利用weather tool软件对适合蒸发冷却空调应用的20个城市，在采用间接-直接蒸发冷却空调技术后的热舒适率进行了分析，并对部分城市提出了蒸发冷却空调应用的优化方案。对蒸发冷却设计分区的4个典型城市应用蒸发冷却空调的热舒适率进行了分析，发现只有位于高湿度地区的重庆市不适宜采用间接-直接蒸发冷却空调方案，对其进行了2种蒸发冷却空调设计方案的对比，结果显示，间接蒸发冷却与机械制冷相结合空调方案的制冷系统季节能效比较传统一次回风机械制冷方案提高了54.1%。
Abstract：
Based on the weather tool software, analyses the thermal comfort rate of indirect-direct evaporative cooling air conditioning applied to twenty cities, where evaporative cooling technologies could be applied compatibly, and gives the optimum schemes of applying evaporative cooling air conditioning in some cities as well. Analyses the thermal comfort rate of evaporative cooling air conditioning applied to four typical cities located in evaporative cooling design region, and finds that the indirect-direct evaporative cooling air conditioning is only unsuitable for Chongqing city located in high humidity area. Conducts two kinds of different design schemes in Chongqing city.The comparison results show that the seasonal energy efficiency ratio for refrigeration system of direct evaporative cooling combined with mechanical refrigeration scheme is higher by 54.1% than that of traditional primary return air conditioning system by mechanical refrigeration scheme.
